seat supportinga'rm being. shown in a' differ Letthe numeral 5 designate the stationary frame worloof.'thej swing, composed of 'tw'o" 'pairs' of inclined bars 6 connected by braces. -7,"-\ v h1ch intersect at 8. Mounted on top of this frame ivfork is a canopy 4 having parallel side bars' 9- which are connected with the 4 upper extremities'of tlieba'r 6. The canopy includes suitable canvas cover 4 10, I TheIframe bars 6 ,at the opposite ends of the swing are connected near the top by rods 12 upon which are mounted sleeves, 13, vl1ich' space the end bars 6 on opposite sidesof the swingan'd make it practicableto formfa rigid frame work. These sleeves 13 also protect the rods 12 and form aielativcly 30 Another fea tureof my improvement conlarge bearing forthe suinginglgarsli. The upper extrem ties of each pair of swinging bars are connected with a sleeve 13 by ime'ans over the sleeve, their parallel depending parts being secured to the bars 14: onbpposite sides by bolts 16. The sleeves 13 form a relatively large bearing for the swinging bars, thus constituting a substantial and durable structure. The individual bars 1a of each pair are connected near their upper extremities by a rod 17.

The platform 18 of the swing is composed of parallel side bars 19 connected by floor strips 20. This platform is pi votal1y connected with the lower extremities of the swinging bars 14 by bolts 21. Each bolt 21 passes through the extremity ofa bar 19' and also-through a perforationformed in a mem-' ber 22 of'a seat-supporting anglearm 23. The upwardly projecting member 24 of the es of U cli s 15 whose upper extremities pass arm 23 1s fixedly connected with the rear zontal,-or with the plane of the '1atf9rm18,

with theiadjacent pair of swingipg bars 14, by bolts 27 upon which the seat is pivotally mounted.

'The lower extremities ofthe swin ing.

bars 14 are equipped with reinforcin p ates 28 which are secured thereto by the golts 21 and additional bolts 29.

As. shown in the drawing, the seat-supporting angle arms '23 are provided with metal 'mem ers. which are securedtdthe lower parts of the members 2a by bolts 30' and project inwardly, forming the-members 22, which are provlded with a numberof perforations 31 for purposes of adjustment.

These metal parts are employed. to give strength and durability to the structure and are particularly valuable inview of the adustable feature of the swing.

Assuming that the SWIBg IS in itsnormal position, or that which'it occupies when, at rest, the angle of the seat 25 witli the swing ing'bars 14, may be ehangedby removing the pivot bolts 21 vand moving the-members j22j inwardly or outwardly :to bringother ee.

for-alions 31 into register with the bolt open; ings in the lower extremitiesfof'the bars 14.

If this movement be inwardly,- the inclination of the seat .ascompared with-the hori will be increased, while if it be 1n the'o" p0 site direction (see Fig. 6) the plane 0 the se at will approach more nearly a parallel this character.;

position with referencetothe plane of the platform. It will thus be seen that this is an important adjustment in constructions of To the rear edge of the seat, a back 32 is hinged, as shown'at 33, the said back being connected with the adjacent bar 14 by chains As shown in the drawing, these chains are -mnected with he bars 14:, while hooks 34 adapted to enter any link of the chain,

are connected with the upper part-of the. 'seat back 32 by means of eye bolts 35. .In ordert'o permit the change of inclinationpf the seat, the chains 33 should be correspondinglyregulated, as will be readily. understood. 1

From the foregoing description theuse and operation of my roved swing will be readily understood. ssuming that the swim is"1nthe position shown by full lines form and seats, are-'given' an oscillating movement. The position of the parts after having reached a pre-determined degree of oscillation, is indicated at the left of Fig. 1

by dotted lines. It will be understood that if the seat-supporting angle arms 23 were so adjusted as to bring theouter perforation 31 into position to receive the pivot bolt 21, the

4 5 in Fig. 1, the bars 14, together with the platposition of the seat would be changed 'to approach the horizontal when the bars are in the aforesaid dotted line osition. This would bedesirable if the me ination of the Iclaim 1s:

Aswing, includin a pair ofos'eillating bars, a seat pivota y. connected with the said bars above their lower'extremities, angle arms rigidly connected at one eiitremity with.
